Screw Oil Press Features

Screw Oil Expeller Application

Screw oil presses are more suitable for medium-sized and small-sized grain and cooking oil processing factories or specialized households. They can press particle oil materials and powder oil materials, such as rapeseeds, cotton seeds, soybeans peanuts and sesames etc.

Screw Oil Presser Working Principle

The screw oil press mainly uses the change of pressing screw pitch size and screw thread depth to reduce the volume between screw pitch and pressing chamber, the oil materials get stronger pressure gradually, thus the oil can be squeezed out of the oil materials. Meanwhile, the high pressure in the chamber and the strong friction generates high temperature, which can improve the oil yield.

Notice

▲The temperature of oil manufacture room should keeps between 15℃ to 20℃. If the temperature is too low, it will affect the oil yield and oil quality.
▲Before pressing, the oil materials’ moisture content should be appropriate: peanuts with 8%—11%, soy beans with 5%—8%, cotton seeds with 4%—6%, rapeseeds with 6%—8%.
▲After running for three to four months, the screw oil press needs a maintenance. Lubricate the machine parts with machine oil at regular intervals.
